| CCC.Core.CP35 | Customer-Managed Encryption Keys | The service may be configured to encrypt data at rest using a key that the user creates and controls in a key management service, instead of a key managed by the provider. |
Related Threats
| ID | Title | Description |
|---|
| CCC.KeyMgmt.TH05 | Keys are Created With Algorithms Not Permitted by Policy | Key creation accepts any supported algorithm and key length, so a key may be created with a curve or modulus that organizational policy or a regulatory baseline does not permit, such as a non-NIST curve or a modulus below the required size. Data or signatures protected by that key then rely on weaker cryptography than intended. Confidentiality and integrity of the protected data are reduced for the life of the ciphertext or signature. |
| CCC.Core.TH18 | Encryption Key is Misused | Encryption keys may be used by an unauthorized entity due to inadequate key management practices or the compromise of a connected system. This could lead to the decryption of sensitive data, impacting its confidentiality and integrity. |
